This is one of the weirdest arguments.
Side A has bathrooms marked Male and Female, want biological males to use the male one, biological females to use the female one. Okay, I'm fine with that.
Side B wants bathroom genders to be so that someone who may have been born a male or female but has permanently and irrevocably switched gender orientations can use the other bathroom. Okay, I'm fine with that, score one for side B.
Not good enough. Side B wants to make it so that someone can ostensibly change orientation on a whim, making the change of genders whenever they please, and making them indistinguishable from someone who might be going into the other gender's bathroom for sexual gratification. I assume, perhaps incorrectly, that going into the other sex's bathroom, dressing room, shower, or locker room for gratification purposes is still considered wrong at this point. Now I'm no longer on board with side B's cause. It's time for side A to push back.
Side A says no, there's problems with that stance, that it makes it impossible for us to distinguish between genuine gender-changers and perverts, which will just make for all sorts of issues and problems. Not to mention having to change the signage and/or structure of every bathroom in every public place in the country. Should we legislate a third gender neutral bathroom for every business?
Side B says well, you just need to stop being so uptight, there's always been trans in the "other" bathrooms, just get over it, it doesn't make a difference who uses what bathrooms, put us all in unisex bathrooms for all we care.
That's when I say this: If you're telling us we shouldn't care what bathroom you use, why don't you just adopt that attitude yourselves, and leave things the way they are? If it's okay for side B to have women and girls put up with men in their locker rooms and showers and bathrooms, if they're gender-agnostic enough to just ignore the "Men" or "Women" labels on the doors, if it doesn't matter if they just made them all "Men/Women/Whoever" signs, why have this fight?
If you don't care about the labels on the doors, and it's supposed to mean nothing to us you which one you use, just do us a favor and go with the one that matches your genitalia. Honestly, what's wrong with bothering less people?
The left today seems caught in a self-contradictory state of being offended by the simplest, most common things, yet they're willing to absolutely maximize the amount that they offend, inconvenience, and create discomfort for others.
